Useful analytics answer specific product questions while respecting the people who use the service.
Start with a decision the team expects to make. Define the events needed to answer it, and record what each metric cannot tell you.
Use consistent event names and document when events fire. Avoid sensitive identifying information in payloads, and apply suitable retention and access controls.
Combine quantitative patterns with user feedback. Review whether the numbers change a decision, and remove tracking without a clear benefit.
